There are a number of things that may happen during the QRS wave. There will be ventricular depolarization and right after absolute refractory period for ventricles will occur.

What initiates the p wave?
cardiac cycle
Is the p wave part of the cardiac cycle?
Yes - On an ECG the P wave is the first wave of the cardiac cycle. It represents the Sinoatrial node which is the natural pacemaker of the heart firing and causing the atria to contract in order to fill the ventricles.
How does the P wave the qrs complex and t wave relate to the electrical and mechanical evemts of the cardiac cycle?
its related to the dialysis
What happens in the cardiac cycle immediately before P wave?
The P wave on an ECG occurs when the sinoatrial node which is the hearts natural pacemaker fires causing the atria to contract. The period just before this when there is no electrical activity is the hearts 'resting' period between beats when the muscles are relaxed giving the atria a chance to refill with blood.
What happens in the cardiac cycle after the p wave?
The T wave on an ECG reading is the last wave in the cycle, and it represents the repolarisation of the heart. This means that the ventricles have just contracted sending blood around the body, and the heart is now 'resetting' itself ready for the next cycle.
The R wave of the ECG is most closely associated with which phase of the cardiac contraction cycle?
Ventricular contraction.
Immediately before the P wave?
The electrical milestone event that occurs at the P wave of the cardiac cycle of the EKG is atrial depolarization. The upward stroke is right atrial depolarization, and the downward stroke is left atrial depolarization. Normally, this lasts for no more than 0.11 sec.
How long is a cycle in a sound wave?
A cycle in a sound wave is the time taken for one complete vibration.
What happens if you wave at the northern lights?
Nothing happens if you wave at them.
What is follicular wave?
during the menstrual cycle, follicular wave is where the time it starts as a tertiary stage follicles to ovulation. the follicular wave consists of each cycle a women (female) goes through the menstrual cycle.
What happens to the wavelength of a wave when the frequency of the wave is doubled but the wave speed stays the same?
Nothing happens
Cardiac markers start to rise in the presence of what?
tell tale signs of hypokalemia is a small upright wave that follows the t wave
